Title: Membrane-electrode assembly for the electrolysis of water
Inventor: SCHAACK KLAUS
IPC: C25B9/23
Filed: 2004-07-14
Abstract: The invention relates to membrane-electrode units for the electrolysis of water ( electrolysis MEE's), which contain: an ion-conducting membrane having a front and rear side; a first catalyst layer on the front side; a first gas distributor substrate on the front side; a second catalyst layer on the rear side, and; a second gas distributor substrate on the rear side. The first gas distributor substrate has a two-dimensional extension that is smaller than the ion-conducting membrane, whereas the second gas distributor substrate has essentially the same two-dimensional extension as the ion-conducting membrane ("semi-coextensive design"). The MEE's also comprise an unsupported free membrane surface that yields improved adhesion properties of the sealing material. The invention also relates to a method for producing the MEE  products. This results in obtaining pressure-resistant, gas-tight and cost-effective membrane-electrode units that are for use in PEM water electrolyzers, regenerative fuel cells or in other electrochemical devices.

Title: Efficient management of cryptographic key generations
Inventor: SELANDER GOERAN
IPC: H04L9/08
Filed: 2004-10-13
Abstract: The invention generally relates to management of cryptographic key generations in an information environment comprising a key-producing side generating and distributing key information to a key-consuming side. A basic concept of the invention is to define, by means of a predetermined one-way key derivation function, a relationship between generations of keys such that earlier generations of keys efficiently may be derived from later ones but not the other way around. A basic idea according to the invention is therefore to replace, at key update, key information of an older key generation by the key information of the new key generation on the key-consuming side. Whenever necessary, the key-consuming side iteratively applies the predetermined one-way key derivation function to derive key information of at least one older key generation from the key information of the new key generation. In this way, storage requirements on the key-consuming side can be significantly reduced.

Title: Method and apparatus of producing belts with precise cord length and tension
Inventor: WOOD DOUGLAS BRUCE
IPC: B29C70/32
Filed: 1996-10-03
Abstract: A method and apparatus for accurately applying a cord (12) to a rotatable mandrel (14) utilizes control of cord length, rather than cord tension, as the control parameter. The apparatus includes a mandrel (14) with an inflatable diaphragm (54) mounted on an outer surface of the mandrel (14). The diaphragm (54) is selectively inflatable via a control valve (58) and source of pressurized fluid for dynamically adjusting a circumference of the mandrel (14) in response to a control input. The control input reads a tension in the cord (12) being wound. The cord (12) is positively fed to the mandrel (14) according to a defined algorithm based on the mandrel's shape, circumference and rotational speed, rather than by demand feed of the cord (12). The apparatus includes a positive feed control capstan (18) which is electronically geared. The apparatus further includes a cord-laying wheel (30) which isolates radially directed forces from circumferentially-directed forces. A second embodiment of the invention includes the belt being rotated on first and second pulleys (14A, 14B) while the cord (12) is applied. A center distance between the first and second pulleys (14A, 14B) is selectively adjustable to control cord tension in the cord (12).

Patent CA-2557993-A1 (CA)
Title: Frequency-based coding of audio channels in parametric multi-channel coding systems
Inventor: HERRE JUERGEN
IPC: G10L19/00
Filed: 2005-02-23
Abstract: For a multi-channel audio signal, parametric coding is applied to different subsets of audio input channels for different frequency regions. For example, for a 5.1 surround sound signal having five regular channels and one low-frequency (LFE) channel, binaural cue coding (BCC) can be applied to all six audio channels for sub-bands at or below a specified cut-off frequency, but to only five audio channels (excluding the LFE channel) for sub-bands above the cut-off frequency. Such frequency-based coding of channels can reduce the encoding and decoding processing loads and/or size of the encoded audio bitstream relative to parametric coding techniques that are applied to all input channels over the entire frequency range.
